Survival rate, weight loss, and body temperature of mice with different type I interferon signaling after SFTSV challenge. Three groups of mice, C57 BL/6 (WT), mice treated with blocking anti-type I interferon-α receptor antibody (IFNAR Ab), and IFNAR knockout (IFNAR⁻/⁻) mice, were intraperitoneally infected with four doses of SFTSV (KH1, 5 × 10⁵ -5 × 10² FAID₅₀). a Survival rates, b body weight (%), and body temperature (°C) were analyzed
